Method Detail

• compressModifiedHuffman

  public static byte[] compressModifiedHuffman(byte[] uncompressed,
                               int width,
                               int height)
                                        throws ImageWriteException

  Compressed with the "Modified Huffman" encoding of section 10 in the TIFF6 specification. No EOLs, no RTC, rows are padded to end on a byte boundary.

  Parameters:

  uncompressed -

  width -

  height -

  Returns:

  the compressed data

  Throws:

  ImageWriteException

• decompressModifiedHuffman

  public static byte[] decompressModifiedHuffman(byte[] compressed,
                                 int width,
                                 int height)
                                          throws ImageReadException

  Decompresses the "Modified Huffman" encoding of section 10 in the TIFF6 specification. No EOLs, no RTC, rows are padded to end on a byte boundary.

  Parameters:

  compressed -

  width -

  height -

  Returns:

  the decompressed data

  Throws:

  ImageReadException

• compressT4_1D

  public static byte[] compressT4_1D(byte[] uncompressed,
                     int width,
                     int height,
                     boolean hasFill)
                              throws ImageWriteException

  Throws:

  ImageWriteException

• decompressT4_1D

  public static byte[] decompressT4_1D(byte[] compressed,
                       int width,
                       int height,

                                throws ImageReadException

  Decompresses T.4 1D encoded data. EOL at the beginning and after each row, can be preceded by fill bits to fit on a byte boundary, no RTC.

  Parameters:

  compressed -

  width -

  height -

  Returns:

  the decompressed data

  Throws:

  ImageReadException

• decompressT4_2D

  public static byte[] decompressT4_2D(byte[] compressed,
                       int width,
                       int height,

                                throws ImageReadException

  Decompressed T.4 2D encoded data. EOL at the beginning and after each row, can be preceded by fill bits to fit on a byte boundary, and is succeeded by a tag bit determining whether the next line is encoded using 1D or 2D. No RTC.

  Parameters:

  compressed -

  width -

  height -

  Returns:

  the decompressed data

  Throws:

  ImageReadException
